ments'in Rotary Glass-Pots,- of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention relates to rotary glass pots. and the. objects of my invention are to provide a 'revoluble pot holder that can be intermittently moved to position pots wherebvthey can be filled andglass gathered or withdrawn from the same, and to provide a glass ot with means, in a manner as will be hereinafter set forth, whereby the glass within the pot can be maintained at a de- Other objects of my invention are to pr0- vide a'glass pot that will reduce the cost of manufacturing various kinds of glassware to a minimum, and facilitate the operation of gathering batches of glass whereby a more uniform product will be obtained without't-he loss of glass.

Further objects of my invention are to furnislra pot with a )lurality of individualreceptacles that can e easily and quickly shifted into position wherelrv a fresh batch of'molten glass will be presented for each gatheringoperation, and to provide simple and cfi'ective'mcans for eparately control- 5 lin; the temperature of the glass in each re- I ceptaele, whereby the glass can be maini tamed at the proper consistency and'tluiditv I 5 u all =rud pipe having a T 19 connected for gathering purposes.-

lVith the above and otherobjeets in view i which will more readily appear as the invention is better understood, the invention resides in the novel construction, combinati-m and arrangement of arts to be herein after specifically deseribec and then claimed.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the-sever" views in which Figure 1 is a side elevation of a in accordance with this invention, "i 2 is a plan of the same, Fig. 3 is a vertica cross sectional view of the pot, Fig. 4 is a plan of the pot with the cover thereof removed. Fig. 5 is a plan of the foundation and heaters of the pot, Fig. 6 is a vertical sectional view of a portion of the pot .ihmvi t'. one of the hcaters and one of the re eptacles i lass pot.

the wall thereof. and Fig. 7 is a horizontal sectional view of one of the gas regulating valves of the pot. I

For a successful operation of the glass put, i is preferable to locate the same in a lp"t I and con rete. lire clay. fir'e brick or ot'ier morfusible n'mtcrial can be used in co".--tructin; the pit and the greater pa rt of the pot. The bottom 2 of the pit is provided with an annular wall and located centrally of the bottom of the pit s a circular base 4. Surroundinc the base 4 is an annular support 5, said support having the Inner and outer walls thereof row-ed at diametrically opposed points. as at 1 for bcaring'blocks-T. Revolublv supported hv said hearing blocks are the spindle i of two sets of rollers 9 and 10. the spindlesol the rollers 10 extending into bearing blocks ll provided therefor in the wall 3 and the spindles of the rollers 9 extending on to hearing.' blocks '12 provided therefor in the wall of the base 4. The rollers of each tlI: eumfersntially arranged set are equally spaced. and the purpose of these rollers wi l presently appear. The support 5 at equally spaced points is provided with oval vertical heater shells 13 having vertical transverse partitions 14 dividing, each shell into two troln ml't'nients 1?.

Embedded in the s't 'iport 5 are U- hapc l burners 16 having the ends thereof extendin; upwardlv into the compartments 1.. of each shell. The l ru'ners 16 are connected by c tvi'ar llv extending pipes 17 to a pipe 13 raugc'l etween the support 5 and the to a gas .ippl pipe 20 that extends thin-och .'\t the juncture of the p pe 17 and the pipe :8 there are regrulatim: valvi- E 3 havint: the stems 22 thereof exten ing through the wail 3. It is only necessary to use two regulating valves t control tlutemperature of glass to be drawn from the pot. as will hereinafter appear.

. Located upon the sets of rollers t) and 10 are circ'ular rings 23 and the former resting'upon the set-oi rollers 9 and the latter upon the set of rollers 10. the ring .24 ha ving a rim .25 flush with the upper edges of the wall 3.- Located upon the rings :23 and 24 is a cylindrical vertical housing '26 having a central vertical opening 27 providing clearance for a pedestal 28 mounted it )on he base 4. 'l he pedestal 28 is ailuptet to support a circular top plate to he hereinafter referred to. Preferably the pedestal .28 is provided with a spider. The housingiivalls. The walls of the housing are'connected bystraight iwebs 30-and curved webs 31 thathave the bottoms lthereofprovided with transverse beams 33 'ad'apted to sup 'ort individual pots or rece tacleS'B t'in t 1e compartments 32. Encircling the-housing 26 is at rack 35. and meshing w ith-saidrack a 'gin'ion .36'carried. by a driven shaft 37 it is through the medium of theQshaft; 37 and the, pin on ter nitt'ently, moved. 5
